Troubleshooting Internet Connection Problems

Some features in Citavi require an Internet connection, such as online search and adding citation styles. If you get a message saying that you don't have an active Internet connection, try the following:

1.	Check Your Internet Connection Check that your Internet connection is working by visiting any website, such as www.citavi.com. If it works, then your Internet connection is working.

Check Proxy Settings
If you are on a university or corporate network, you might connect to the Internet through a proxy server, which acts as an intermediary between you and the Internet. Citavi supports proxy servers, either one configured in Windows (Start > Control Panel > Internet Options > Connections), or one set specifically in Citavi (Tools > Options > Search > Proxy settings). In either case, you need the proxy settings from your system administrator. If you are using the Windows proxy settings, check whether you can load www.citavi.com in Internet Explorer (other browsers use independent settings and are not affected by the Windows proxy settings).
Hint: If it doesn't work even with the correct settings, try selecting the Compatibility mode for HTTP 1.0 proxies checkbox in Citavi's proxy settings.

Check Firewall Settings
A firewall filters Internet traffic to and from your computer, in order to add a level of security.

There are several kinds of firewalls. The most common kinds you may have installed on your computer are ones configured by port number, and ones configured by application. Make sure that Citavi is allowed in your firewall settings.

Citavi uses the following ports:

Port	Used for
80	Checking for updates to the Citavi program, transformers, citation styles, and available online resources.
80	Online resources accessed via Web services or other HTTP requests.
210, 20010	Online resources using the default ports for Z39.50. If a strict firewall blocks this, Citavi will route the request through the Citavi Web service on port 80.
Any	Online resources using nonstandard ports for Z39.50. If a strict firewall blocks this, Citavi will route the request through the Citavi Web service on port 80.
